Question
Does the brand of soda affect how long it fizzes?
Hi Alyssa -- yes, different brands have different amounts of carbonation. It's measured in 'volumes of Co2' which is how much CO2 they've pumped into the soda and dissolved.
Other things that affect how long it will fizz are the temperature of the soda (colder soda fizzes longer), and the altitude at which you open it (fizzes longer at lower altitudes).
You'll even find variations in the same brand of soda in the same 6 pack -- it's not always consistant.

Expertise
Though my experience is mostly in the fields of electricity, magnetism, and physics, I have a broad science background. My career is in the field of alternative power sources -- solar, wind, water and battery power. But any questions about electricity, magnetism, energy conservation, power generation, electric motors, and even general physics are very welcome--especially from kids. They ask the best questions of all! I pride myself in answering science questions accurately, with ideas for SAFE, easy experiments that kids can perform by themselves--and that let them prove the answers to their own satisfaction. I think science should be fun, and available to everyone, regardless of age.
Experience
I have volunteered in our local public schools for 5 years. I currently make presentations at our schools about electricity and magnetism, with a focus on solar, wind, water and other alternative power sources. I try to demonstrate at our schools how easy it is to make electricity, with simple devices using spinning magnets and coils of wire--powered by wind, water, bicycles, gerbils...etc. And of course solar panels! I am the webmaster of Otherpower.com, an alternative energy website. I have lived 10 miles from the nearest power pole for 11 years--I make all my own electricity from scratch with sun, wind and water.
